UPDATE:
SPL bushings for the diff and subframe arrived last week and went into the car this past weekend. Aside from time consuming, the process was fairly linear: I managed to remove and install the subframe bushings on Sat and finished the diff and rest on Sun.
Ass up in the air:
After a few hours or work - subframe is out:
The main reason for the work:
Driver side front subframe bushing
Passanger side, knew it was bad but didn't know just how bad:
Burning the old bushings out. I tried popping the collars as suggested but that didn't work for me so I used the old sawing technique.
Used a tool to push brake pistons and some washers (Pep Boys or Autozone sells them ~$20 iirc) for the subframe bushings.
Bolt was too thick for the diff bushings so I rummaged through my bolt bucket and used what appeared to be a bolt from an alternator or AC unit with a 14mm nut (no pics, too dark by then)
Next day all ready to install. Used a wire brush and some shop towels with Liquid Wrench to do a quick clean up:
I did this all by myself without help which I don't recommend doing but shows that it can be done.
Driving Impressions:
Went to grab some food/test the car on Sunday and brought the car to work today.
The rear of the car feels a whole lot more solid and 'planted'. No more wandering around, better grip.
The bad: vibration and noise. Not friendly to bad roads (I drive on the 405).
Overall, a huge improvement but not great for a daily. I've daily driven cars with modded suspension in the past so I'm not complaining.
I still need to thinker some more with the front and alignment.
This is on 17X9 rears and stocker fronts; stock open diff and cruddy oem struts.
